Are you sure this is the right package list for a desktop installation? I don't think virtuoso-* should be included. Could you check your /var/log/apt/history.log for new packages?

Yes - definitely - CD install not the DVD install. history.log showed two packages. Maybe these are included in the default install for people who want to install into VirtualBox or its open-source equivalent.

Perhaps I need to find out which packages are installed in a minimal environment and the extra packages installed by [..what?..] (tasksel?)

I did a new install using the Alternate CD and used this answer as reference for installing additional packages. I also found out that the virtuoso-* packages are a database thing.
